The objective of earthing or grounding is_______________?
Correct answer: A. to provide as low resistance possible to the ground
- A. to provide as low resistance possible to the ground
- B. to provide as high resistance possible to the ground
- C. to provide flow of positive, negative and zero sequence currents
- D. none of the above
Explanation
Earthing provides a low-resistance path for fault current to flow safely into the ground, allowing protective devices to operate quickly. High resistance would leave dangerous touch voltages on exposed metal parts.
